Japan Orders Mass Evacuations as Double Storm Threat Intensifies, Taiwan Paralyzed by Torrential Rain

East Asia is facing a major weather emergency as Japan prepares for the impact of multiple storm systems while neighboring Taiwan struggles with severe flooding caused by torrential rains linked to Tropical Storm Mekkhala.

Authorities in Japan have ordered more than 2.2 million residents to evacuate vulnerable areas as heavy rainfall, strong winds, and flood risks intensify across the country’s western and southern regions. The storm system, which passed near Taiwan before moving toward Japan’s Ryukyu Islands, has already caused significant disruption across both territories.

Japan’s Meteorological Agency warned that a stationary seasonal rain front, combined with warm, moisture-laden air from the approaching storm, is generating exceptionally heavy rainfall. Officials have issued alerts for flooding, landslides, swollen rivers, and dangerous travel conditions.

The severe weather has already disrupted transportation across Japan. More than 200 flights have been canceled, train services suspended, and several major expressways closed. Manufacturing operations have also been affected, with automaker Toyota temporarily halting production at one of its facilities in the southern island of Kyushu.

Meanwhile, Taiwan is grappling with widespread flooding despite the storm not making direct landfall. The outer rain bands of Mekkhala unleashed torrential downpours across the island, particularly in the southern regions of Kaohsiung, Tainan, and Pingtung. Authorities closed schools and government offices, leaving approximately six million people affected by the weather emergency.

Floodwaters inundated streets and neighborhoods, while severe flooding in Tainan forced the shutdown of a section of Taiwan’s critical north-south railway line, disrupting transportation across the island. Local authorities reported nearly a meter of rainfall in some rural areas of Pingtung County.

The storm has also heightened concerns in eastern Taiwan’s Hualien County, where authorities evacuated nearly 200 residents living downstream from a rapidly expanding barrier lake formed by landslides in mountainous terrain. Officials fear that a breach could unleash destructive floodwaters similar to a previous disaster that claimed lives in the region.

Despite the widespread disruption, no fatalities have been reported in either Japan or Taiwan as of Friday. Emergency services remain on high alert as meteorologists forecast continued rainfall over Taiwan for at least another week, although conditions are expected to gradually improve.

Experts note that while the intense rainfall poses immediate dangers, it may also help replenish Taiwan’s reservoirs, which depend heavily on seasonal typhoons after typically dry winter months.

Regional authorities continue to urge residents to monitor official weather warnings, avoid flood-prone areas, and prepare for possible further disruptions as the storm system moves northward toward Japan.
